Hey there.

A lot of that list is in BS 7671, havn't got mine to hand right now so can't help with page numbers sorry, but if you have access then you will find most of it in there.

Ins Res values are 0.5ohm, 1ohm and 1ohm for 250V, 500V and 1000V.

All the loop values are in there, testing sequences, electrostatic precautions. Need to get a hold of the regs book mate, she'll see you right.

i have the reg's book and on site guide!

Guess i need to dive though it and find some page numbers

All the max earth fault loop values are on pages - 48, 49, + 50 of ol' red
Transient voltages - ol' red
Test sequences will be in OSG/GN3
UPS ol'red

Seems like some of it would be in your course notes - restoration of building fabric, disposal of waste, downtime.

Types of fault - short circuit, overload, line - earth, neutral - earth, line - line

Some of us did our training before the C&G 2330 course (I'm assuming this is what you mean) even existed. That is why not every spark has done it!

We were doing our best to help with your query even though we aren't familiar with the exam you mention.

ok so exam tomorrow that means a whole day of revising, or is it really worth it if it's an open book exam?
